Netgear AirCard 815S (AT&T)

I know as much about technology as I do about a horse pulling a honey-wagon. I put in an AT&T SIM card. But I’m getting “Registration Error: SIM Provisional -MM#2”. And “Data Connection Disconnected: Your data connection is disconnected. Check settings > Broadband for options”. I didn’t realize until I got it that it’s used and came with no instructions. Your help would be most appreciated.
